Sustainable Stormwater Options

Last updated Nov. 22, 2017 - 4:42 pm

There are many stormwater options that residents and businesses can install on their property that qualify for funding through the Stormwater Quality Cost Share Program.

(Please note: While most projects may receive 75-90 percent reimbursement for a project, the total amount funded by the City of Raleigh varies based on project type and materials used.)

Rain Gardens

Joyner Elementary

Rain Gardens are a nice addition to a yard's landscaping. Its plants and soil also remove pollution from stormwater and allow water to soak into the ground. 

The rain garden at Joyner Elementary Magnet School in Raleigh treats stormwater runoff from the school's roof using the garden's plants and soil to capture and clean stormwater before it reaches storm drains and local waterways.

Average Price: $20,000 - $50,000

Backyard Rain Gardens

St. Ambrose Episcopal Church Rain Garden

Rain Gardens are a nice addition to a yard's landscaping. Its plants and soil remove pollution from stormwater and allow water to soak into the ground. 

The 500-square-foot rain garden at St. Ambrose Episcopal Church treats stormwater runoff that comes from the church's parking lot and rooftop. 

Average Price: $1,500 - $5,000 (Price may vary based on rain garden type)

Permeable Pavement and Pavers

Residential Permeable Pavement

Permeable Pavement and Pavers can be used in place of typical pavement to allow rainfall to absorb into soil that is on residential or commercial properties.

This 900-square-feet of permeable pavers collects stormwater runoff from about 1,500-square-feet of the impervious space on this residential property. 

Average Price: $10,000 - $30,000

Cisterns

cistern at Walnut Creek Wetland Park

Cisterns collect rainwater that is great to re-use for watering landscapes and washing cars.

The 2,200-gallon cistern at Walnut Creek Wetland Park collects stormwater runoff from the building's roof and is used to wash equipment and water plants.

Average Price: $5,000 - $40,000 (Price may vary based on cistern type)

Green Roofs

Buffaloe Road Green Roof

Green roofs cover a traditional roof with plants and soil that capture rainfall and reduce water pollution.

The green roof at Buffaloe Road Aquatic Center helps to slow stormwater runoff when it rains. It also keeps the building a little cooler, too! 

Average Price: $100,000 - $250,000

Stormwater Wetlands (Water Garden)

Stormwater Wetland at Fred Fletcher Park

Wetlands are one of the most effective ways to treat stormwater runoff.

The constructed wetland (water garden) at Fred Fletcher Park in Raleigh treats stormwater runoff while being an amenity to the neighborhood and providing natural habitat for aquatic creatures.

(The Fred Fletcher Park Wetland was not completed through this program, but is a good example of what can be done.)
